I've heard that with most rifle platforms there's a trick where a zero at 25 yards is the same as a zero at 100 yards for what you could consider "average" or "typical" ammo. Is this true with AKs? I'm going to be sighting in my irons when my sight tool gets here, but I need to know where to zero. Most readily available is a shorter range where I can get 25 yards easy. Will that work or do I need to find a 100 yard range to do it right?

wow. that was an absolutely amazing video. and after looking at the construction of the field adjustment on my ak, it looks like if i zero at 25, then i can use the slider to help make the POI match the POA at the marked ranges, rather than approximate a combat effective shot. that's an incredible source. thank you so much. now i feel like i have a clue as to what i'm doing.
